FEED-GAGE FOR PRINTING-PRESSES.

' SPECIFICATION forming part of Letters Patent No. 393,480, datedNovember 27, 1888.

Application filed June 3, 1884. Serial No.133.604. (Model) To all whom,it may concern.-

Be it known that I, EDWARD L. lVIEGILL, a citizen of the United States,residing at Brooklyn, in the county of Kings, State of New York, haveinvented a new and useful Improvement in Feed Gages for Platen Printing-]?resses, of which the following is a specification.

My invention relates to feed-gages used on the platen ofjobprinting-presses for registering sheets; and the object of my inventionis to produce an extensible feed gage with parts arranged to slide ormove lengthwise of each other and have the forward end suitably constructed to gage the sheet and the lower end pivoted at or near the edgeof the platen, whereby the feed-gage is lengthened, shortened, andturned laterally and secured in various positions.

In the accompanying drawings, Figure 1 is a plan view ofthe platen ofaprinting-press with three of my feed-gages attached. The dotted linesshow the sheet and feed gages transferred to different positions. Fig. 2is an enlarged perspective View of one of the feed-gages removed fromthe platen. Fig. 3 is an edge view of same.

()f the printing-press, V7 is the platen; X, the platen bail; Y, theplaten paper, and Z the sheet fed to the gage heads.

The sliding section A, having at the forward end a gage head, a, andelastic pivoted tongue I), is slotted through nearly its entire length,and operated upon and secured to the lower pivoted section, B, by meansof a thumbscrew, 0, and stud d, which pass through said slot. Byomitting the stud d the result of lengthening and shortening the gagesis still maintained, although I prefer to use the stud d to keep thesaid sections parallel. The holder or bracket 0, which supports the saidsections on the platen, and to which said section B is pivoted, iscomposed of the knee e, which is widened to better brace it between thebail and the platen, and is bent, as heretofore, under and around thesaid bail in a solid sheet or one or more narrow strips, ff, so that itwill remain on the bail when raised from the edge of the platen and g0readily with it when pushed down again to fasten the platen paper. Theupper end of the. knee 0 is folded over to form a jaw at g, whichextends between the pivoted end of section B and the thumb screw or nuth.

The sliding section A (or sections, as intermediate ones may beemployed) admits of a direct adjustment to and from the sheet, and maybe run down about half-way between the center and the bottom edge of theplaten, while the pivoted section B admits of a circular adjustment, andmay be turned down so as to bring the gage-head the rest of the way tothe edge. Thus, without moving the holders or extending the parts farbeyond the platen, the distance is covered from center to bottom edge.By the combined movement of the sliding and pivoted sections with theholders, by sliding and turning the former and moving the latter alongthe platen-bail, the gage-head may be brought to any spot on the lowerhalf of the platen, and by tightening them with the screws a rigid holdis insured. The screws, however, may be omitted where friction alonewill be suificient to hold the parts in position.

Any form of device for pivoting the feed gage at the edge of the platenmay be em-' ployed, and the parts may be connected by any suitablearrangement.

The side guides may be secured by either the upper or lower platen-bail.

What I claim is 1. An extensible feed gage consisting of parts slidingor moving lengthwise of each other, and having the forward endconstructed to gage the sheet and the other end pivoted at or near theedge of the platen, substantially as herein described.

2. The combination of the gage head. a, tongue I), slotted section A,screw 0, lug d, and pivoted section B, all arranged substantially asherein described.
